Development of Polymeric Composite Materials Based on Alcoholysis Products of Secondary Polyethylene Terephthalate

The effects of polyethylene terephthalate secondary alcoholysis conditions on the structure and particles of hydroxyl-containing polyester polyols were investigated. The dependence of the physicochemical package of hydroxyl-containing polyester polyols on the amount in the reaction medium was established. A mixture of unsaturated polyesters based on polyethylene terephthalate alcoholysis products containing mixed waste was investigated. The structures of the alcoholysis products and the unsaturated polyesters based on them were investigated by IR spectroscopy. The technological package of unsaturated polyesters synthesized on the basis of alcoholysis products of secondary polyethylene terephthalate meets the technical requirements for the production of polymer composites and glass fiber pipes. The effect of hardener system on the curing process is shown. Unsaturated polyester brands “PN-Mama-02”, “PN-Mama-03A”, “PN-Mama-03” show that polymer composite pipe products can replace imported “Body” brand resin I’m here.
